On iPhone devices , Apple provides a sound isolation feature for use during cellular calls, in the operating system iOS 15 and later, and Apple includes many new features to make video conferencing using FaceTime and other video calling applications more attractive. One of these features, called sound isolation, makes... It's easier for people to hear your voice on a video call, and in iOS 16.4 and later, it's also available for use on regular phone calls. When you're on a call, your device's microphone typically picks up a wide range of sounds in the environment, but with sound isolation, machine learning distinguishes these sounds, blocks out any ambient noise and prioritizes your voice so it comes through clearly.
The following steps show you how to enable sound isolation when making a regular call on an iPhone running iOS 16.4 or later.
1- Open the Phone app and start a regular voice phone call with someone.
2- Once you're in the call, pull down the Control Center by swiping diagonally from the top-right corner of the screen (if your iPhone has a Home button, swipe up from the bottom).
3- Press the microphone mode button at the top.
4- Select the sound insulation option.
5- Sound isolation will now be activated, and you can turn it off at any time by simply accessing the Control Center again and choosing Standard.
When Apple originally introduced FaceTime's sound isolation feature, it also launched another audio option called Wide Spectrum, a feature that the company says can capture "an entire audio symphony — your voice and everything around you." Essentially, this mode brings every sound to Your call, which is perfect when you want the other person to hear everything that's happening in the space you're in. Note that the Wide Spectrum app isn't available for regular phone calls — it only works with FaceTime.
